The second-ever commercial landing on the moon comes amid a flurry of lunar exploration activity that will see around a dozen ...

These currents, in turn, produce their own magnetic field, which can be detected by instruments like those on the Galileo probe. Second, the presence of a subsurface ocean alters how the magnetic ...

Space missions have set out to search for alien life in the hidden oceans across our solar system - and now, researchers might have a new one to investigate. A new study has strengthened the ...

In the 1990s, however, NASA's Galileo spacecraft captured magnetic measurements near Callisto that suggested that its ice shell surface—much like that of Europa, another moon of Jupiter—may ...

NASA's Galileo mission, which launched into space in 1989, was designed to study Jupiter, its moons, and its surrounding invisible magnetic bubble, called the magnetosphere. The spacecraft had 35 ...

Normally, engineers track spacecraft using signals from stations ... which includes GPS used in the United States and Galileo, a similar system used in Europe. The signals contain information ...

But for both GPS and Galileo the signals are a bit wider than the Earth, so they spill past into space beyond. And so as a spacecraft, you can pick up these spillover signals, we call them ...
